What it does
Evanflow Coder Overseer is an agent skill from evanklem/evanflow. Orchestrate parallel implementation with coder/overseer pairs. Coders implement decomposed tasks using evanflow-tdd; overseers review each coder's output for bugs, gaps, errors, AND cohesion violations against a shared contract. A final integration overseer checks cross-coder cohesion. Use for plans with 3+ truly independent tasks that share an interface contract.
Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Test-driven development. The repository describes itself as: A TDD-driven iterative feedback loop for software development. 16 cohesive Claude Code skills walk an idea from brainstorm → plan → execute → iterate, with checkpoints throughout.
When your agent uses it
- Plans with 3+ truly independent tasks that share an interface contract
- Tasks that involve Test-driven development
Example prompts
- “/evanflow-coder-overseer”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Author the Cohesion Contract (with Test Specifications)
- Decompose into Coder Tasks
- Spawn Coders — RED Checkpoint First
- Spawn Overseers — One Per Coder
- Spawn the Integration Overseer
- Reconcile
- Stop and Report
What it can do on your machine
Read from SKILL.md and the folder at commit c9ae21f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Evanflow Coder Overseer loads about 3.9k tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 2,024 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,024 words (~3,862 tokens).
